- Q:It was when processing a workpiece, processing spindle stops suddenly (other are normal) a check is, I jump out of the inverter, I can click on a processing, and then processing not long after they happen, (do not open the machine spindle machining will also be the case)
- Has the frequency converter been used for a long time? The inverter power placed on the two day, and then open, put the line inside the head plug again, and then boot general can solve the problem, new don't try
- Q:How does frequency converter realize variable frequency speed regulation?
- The technique of alternating current control by changing the frequency of alternating current is called frequency conversion technology. The frequency converter usually uses the on-off function of the power semiconductor device to change the power frequency power to another frequency energy control device.
- Q:What is the working principle of elevator frequency converter?
- Elevator inverter is generally voltage type AC DC AC converter. The basic construction consists of three parts:1, rectifier circuit, alternating current into direct current2, DC bus, energy storage link, the completion of reactive power exchange in the link, the inverter can obtain higher input power factor.3, inverter, DC inverter to variable frequency and amplitude of alternating current, so that the motor work at different speeds.For detailed transducer principles, see attachment.
- Q:How does the PLC process the inverter output signal?
- 1. The analog signals of the converter (such as the 4~20mA signal) are received in the analog input module of the PLC (for example, the EM235 module)2, the input signal processing (32000 digital quantity into 50HZ frequency signal)3. Compare the resulting frequency signals with their own internal settings
- Q:Can the motor with frequency converter directly wave the insulation?
- May notBecause the shaking meter used when shaking insulation, although the output is direct current, but after conversion, the voltage will exceed the rated voltage of the motor much, the only way to test the motor winding to the ground and interphase insulation.
- Q:How to choose frequency converter?
- 1. the power of the inverter is selected according to the load power. How many power motors should be chosen for a multi power motor?. Size one is ok.2. frequency converter model, different uses, choose different frequency converter. For example, there are general frequency converter, fan, water pump dedicated inverter, a machine tool spindle dedicated inverter. Wait。
- Q:What does "EPCU" mean in a frequency converter?
- This code indicates external signal interference.It is possible that the power line and the signal line are coming together to check that the ground of the converter is ready.If not yet, that can only be considered in the inverter output end of the inverter output filter, or inverter output reactor to try.Frequency converter (Variable-frequency, Drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the power supply frequency of the motor to control AC motor power control equipment.
- Q:What does the base frequency 60Hz represent in the inverter?
- For example: if the rated frequency of the motor is 20HZ, the fundamental frequency should be set to 20HZ; if the rated frequency of the motor is 33.3HZ, the fundamental frequency should be set to 33.3HZ; if the rated frequency of the motor is 50HZ, the fundamental frequency should be set to 50HZ; if the rated frequency of the motor is 60HZ, the fundamental frequency should be set to 60HZ; if the rated the working frequency of the motor is 100HZ, the fundamental frequency should be set to 100HZ.
- Q:Can a power converter be used in a motor with small power? Will it burn the motor?
- Can a power converter be used in a motor with low power, depending on your load and what type of converter is it?.If it is only a common fan, water pump or light load operation, then basically no request, you can use, as long as the relevant parameters can be set.
- Q:Where is the difference between soft starter and converter?
- The soft starter changes the supply voltage only and is equivalent to a step-down starter. The frequency converter is much more complex and much more expensive than the soft starter. The inverter also has a soft start function, which is achieved by changing the power frequency. Difference between high voltage starter and low voltage starterThe main circuit of the soft starter is thyristor, and the start-up process is completed by gradually changing the turn-on angle of the thyristor. This is the basic principle of the soft starter. In the low-voltage soft starter market, a wide range of products, but high voltage soft starter products are still relatively small. High voltage soft starter is the same as low voltage soft starter, but there are some particularities in high voltage soft starter and low voltage soft starter:
